What and where are these sketches of Abe Lincoln?

I have to be perfectly honest, this idea occurred to me out of the blue, and it seemed too quirky to pass up. This is simply a collection of sketches of Abe Lincoln. (Use a penny if you need inspiration.)

Lincoln Street runs east and west. Head west on SE Lincoln until it dead ends at Grand. Look across the street and to your right, and see the wall of sketches.
